MM cuts out! Ideas?

Hello,

Argh! My MM has been running great in my truggy for the past year and now with one week to go before the big RC Monster Bash, it flakes out on me!

Here is the deal, I race it weekly at a small track. Last week, during one of the qualify rounds, I landed a double and there was no power. I think I had steering but there was no throttle. It coasted a bit, then stopped, then a few seconds later, it was back to normal. I ran the rest of the round and ended up winning the main.

This weekend, same kind of thing, only it happens during the main while I'm leading and I end up coming in 3rd. I'm pretty sure I had steering but I'm not positive. The whole event lasted about 15 seconds.

I don't know what to do! It always seems to happen when landing a jump. It actually happened to me several months ago during a practice session. I opened the MM up and blew the dust out of it and never had the problem again till last week.

My plan is to rewire the whole thing. I really don't want to do this as I hate to solder those wires onto the little circuit board of the MM but I don't know what else to do. One of the guys at the track suggested I remove the on/off switch. He said it seemed exactly like the switch went to off for a second and then it was unable to calibrate because I was on-throttle.

What do you wizards think?

Please advise, any suggestions would be appreciated - I'd hate to have this problem next weekend at the Bash, I will have one day to test it out as I will be doing some club racing on Saturday.

Thanks guys!
